Pool Dose Pro: Pool Calculator

Your chlorine reads fine and the pool is still green. You added something last week and it got worse. The guy at the pool store sold you a bucket of something and you're not sure why. Pool Dose Pro tells you what to put in your pool, exactly how much, and — just as often — tells you to put nothing in at all. WHAT IT DOES • Tells you the amount, in the units on the bottle you're holding • Tells you when adding more will make the problem worse • Warns you before you do something you can't undo • Works entirely on your phone. No account, no sign-up, no waiting WHAT MAKES IT DIFFERENT Most pool apps are a calculator. You put numbers in, a dose comes out. This one makes a decision. If your alkalinity is high and your pH is low, every calculator will hand you a dose of soda ash — and your water will get worse, because soda ash raises alkalinity too. Pool Dose Pro tells you to aerate instead, and adds nothing. If your stabilizer is climbing toward the point where chlorine stops working, it tells you how much longer your tablets can last — before you buy another bucket, not after. If the fix is new water rather than a chemical, it says so plainly instead of selling you a dose that won't work. That judgment is the product. The arithmetic has been in the back of a test kit for forty years. WHO IT'S FOR Homeowners. New pool owners. Anyone who just inherited a pool and is now responsible for it. If you know what you're doing, you probably don't need this. If you don't, that's exactly who it was built for. WHO BUILT IT Twenty-three years of commercial pool service in Las Vegas — hotels, apartment complexes, HOAs. Every rule in this app came from watching what actually happens to water, not from a chart. HONEST LIMITS This app does not test your water. You'll need a decent test kit or strips, and the app is only as good as the numbers you feed it. There's no account, no cloud, and no subscription pestering you every week. The app never sends your information anywhere - the only links inside it open its published sources in your regular browser. And it will never tell you a chemical is safe to mix. Read the label on the container. Every time.
